Best power-line adapters of 2015

Power-line adapters are devices that turn a home's electrical wiring into network cables for a computer network. They come in handy when you need to bring the Internet connection to a far corner in the basement where Wi-Fi signals can't reach. A power-line connection is generally also more reliable than a wireless connection. With speeds up to 500Mbps, it's also faster. Here is a list of five of the best power-line adapters or adapter kits on the market. Note that you need at least two adapters to make the first power-line connection.
